(54) DISPLAY APARATUS


(57) A display apparatus includes: a substrate having a bending area between a first area and a second area; internal conductive lines on the substrate in the first area; external conductive lines on the substrate in the second area; an organic material layer covering the bending area and covering at least a portion of the internal conductive lines and the external conductive lines; and connection lines on the organic material layer and connecting the internal conductive lines to the external conductive lines, respectively. Organic through-holes are defined through the organic material layer, the connection lines are respectively connected to the internal conductive lines through the organic through-holes, and an upper surface of the organic material layer between the organic through-holes has a convex curved shape.
